Some of us learn optics or other facets of science more readily by manipulating devices and observing the results. Others are more prone to formulate an experiment abstractly and to predict results through mathematical variations, of the parameters. In other words, some of us. are experimentalists and others are theoreticians. I believe that optical education should not stress one of these approaches to the exclusion of the other. Undoubtedly, I will receive no strong opposition to that remark.
